Abstract

Circular management of resource flows is an operational problem that appears with greaterseverity in an historical urban landscape due to the constraints generated by road fabrics and bythe need to protect its values. It often happens that the degradation generated by the irresolutenature of the technical-environmental issues related to the service management, affects both thevulnerability of the historical city characters and the involvement of different actors.Here, we present the results of a research work that, through a case study, develops theexperimentation of a methodology that identifies criteria for a waste collection system planning inan urban landscape of high historical and artistic value.The planning of the operational phase involves the installation of several devices essential forthe correct management of waste collection, in terms of comfort for the user who gives theconsumed material and for the administration that must dispose of it. The experimentedmethodology is divided into three phases: analysis, hypothesis and evaluation, each indispensablefor the development of the next phase and all complementary to each other.The reading of the urban system brings out the tangible and intangible specificities by which it ischaracterized and is aimed at their preservation and enhancement. The morphological-structuralcomponents are analyzed in their environmental and technological system and the cultural andimmaterial components through a qualitative and -quantitative study that assesses the presenceand the influence degree on the territory of observation criteria relating to the perceptive, symbolicand cultural areas.Reference is made to an elaborate information system aimed at a preliminary analysis of themorphological and infrastructural characteristics of historical cities both above and below streetlevel. In particular, the knowledge of the place is aimed at preserving the landscape-perceptivefactors of the buildings, wishing to have a positive impact on the service management, throughoccasions of physical recovery of urban spaces as well as infrastructure recovery.If the physical elements of the urban system are objectively visible and measurable, theideological sphere has been enriched by memories and values in successive events and actions,which today provide a physical space with a concentration of non-tangible, non-visible andtherefore non-measurable characters. We use a multi-criteria evaluation that is able tosimultaneously consider several evaluation criteria with different dimensions, allowing us to takeinto account the elements of social impact that cannot be expressed in numeric terms.In an urban area with a strong historical and cultural connotation, in particular, the rethinking ofa new waste flow management can become an opportunity for the redevelopment of the area andthe context around it, both from a physical-morphological point of view and from a social point ofview, involving the user as an active part in a process of environment renewal. These opportunitiescan be generated upon the condition that the new planning preserves the sensitive characteristicsof the urban landscape.The impact of configured scenarios is evaluated using criteria and sub-criteria which aim toascertain in advance if the necessary transformations for their realization can determine analteration to the existing site and the possible degree of tolerance for their acceptability.
